IMPROVEMENT IN CAR DING-ENGINES.

Specification forming part of Letters Patent No. 191,395, dated May 29,1877; application filed December 18, 1876.

To all whom it may concern Be it known that I, ROBERT F. BARKER, of thecity of Providence, in the county of Providence and State of RhodeIsland, have invented certain new and useful Improvements inOarding-Engines 5 and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

Figure 1 is a side elevation of my improved carding-engine, showing theconnections and the means whereby the relative speeds, at which thediflerent parts are run, are produced. Fig. 2 is a vertical sectionthrough the line ab in Fig. 1. Fig. 3 is a vertical longitudinal sectionthrough the line 0 d, and shows the relative positions of all the parts,the needles or wire hooks being all shown arranged in their properdirection to perform their proper functions. Fig. 4 is a horizontalsection through the center of the main cylinder, the doffer, and thelicker-in on the line 6 f.

Similar letters of reference indicate corre sponding parts in all thefigures.

My invention relates to improvements in carding-engines; and consists inproviding the same with alternate combing and cleaning rolls, araising-cylinder, and impurity-roll, arranged to raise and clean thefiber after the latter has passed the combing-rolls, the whole operatingin connection with the main cylinder of a carding-engine.

In the drawings, a is the fiddle-stand, in the slot of which the shaftof the lap-roll is placed. The fiddle-stand is provided with a bracket,a, arranged to receive theshaft when first placed on the stand, andenable the operative to place the lap-roll into the slot withoutinjuring the lap.

b is the supporting-roll on which the laproll rests, and by which thelap is unrolled and fed to the carding-engine.

c e are the feed-rollers, which feed the fiber to the licker-in roll.

E is an open grate, made up of bars arranged so as to allow the loosedirt and impurities to pass between them.

f is a concave plate, fitting closely to the licker-in roll, andconnected with the vertical partition f. This concave plate protectsthe.

licker-iu from the blast of the main cylinder A, whose surface, movingat a high speed, produces a strong blast of air, which, being exertedagainst the licker-in, has a tendency to force the fiber between theneedles, so that the combing-rolls is carried to, or nearly to, a pointopposite the center of the combing-roll,

and is taken off from the same and again brought in contact with themain cylinder A by the comb-cleaner rolls h h h, each combingroll beingfollowed by a comb-cleaner roll, h.

Any number of combing and cleaning rollers may be used, each pairrepeating the operation.

The combing and clearer rolls must be of the'same, or nearly the same,diameter. They both turn in the same direction; but the wires or needlesare bent, keened, or set in opposite directions, as will be seen in thedrawln s.

I Sy thus raising the fiber off the main cylinder by the combing-rollerand returning the same to the main cylinder by the comb-cleaner, of thesame or nearly ,the same diameter as the combing-roller, all tendency toroll the fiber is avoided, and the fiber is at each operationstraightened and evened, and when it has passed through the successiveoperations a straight even fiber is produced.

As the fiber is prevented from passing around the combing-roller, and isalways returned to the cylinder, a carding-engine will produce a largerquantity of work and still have a much smaller quantity vof fiberoperated upon at any point, thus producing a better quality of work withless power, and also preventing all waste.

The fiber being new in the .bestpossible condition, straight and loose,all leaf and impurities being but feebly retained, the same may beeasily separated, andto accomplish this I place the raising-cylinder 0'close to the main cylinder A, and rotate the same at a greatersurface-speed than the main cylinder, and thus raise the fiber off themain cylinder.

is is the impurity extractor, which separates all leaf, dirt, and ,neps.or small balls of tangled fiber, and delivers a portion of the sameinto the receptacle or box m. Above the box m, and between the dirt orimpurity roll 70 and the main cylinder A, I place the adjustable knifel.

The main. cylinder, taking hold of the fiber, draws the same over theknife-edge, and lays the same straight and even on the cylinder A, andin this condition it leaves the cylinder, and is taken up by the dofl'ern.

To prevent atmospheric suction the partition 0 is made to extend upwardbetween the main cylinder and the doffer.

The main cylinder, perfectly clean now, passes onto the licker-in torepeat the operation. 'Some of the light leaves will still adhereloosely to the under sideof the fiber, and to separate this I place theadjustable knife- 7 plate 1), as shown, which separates all theloose'leaves and deposits the same in the leafbox. The fiber passes ontothe front of the doffer, and is taken off by the comb-stock straight andeven, free from leaf and other impurities, and without having lostaparticle in waste.

When properly built and proportioned, this carding-engine maybe used forall kinds of fiber, and most of the improvements may be connected with.carding-engines now built.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1 The combination, with the cylinder 5 andimpurity-roll k, of the receptacle m, arranged to receive and collectthe impurities, substantially as specified.

2. Acardingengineprovided with alternate combing and cleaning rolls, araisin g-cylinder, and impurity-roll, arranged to raise and clean 'thefiber aft'er the same has passed the combing-rolls, the whole operatingin connection with the main cylinder, as and for the purpose described.

In testimony that I claim the foregoing as my own I have affixed mysignature in presence of two witnesses.
